PROBLEM TO BE SOLVED: To provide a medical electrostimulation electrode and a medical electrostimulation apparatus having electrodes of which positions are hardly deviate from desired positions.SOLUTION: The medical electrostimulation electrode comprises: a long lead section 3 including a distal end and a proximal end an electrode section 10 mounted to the distal end of the lead section and including electrodes for exerting electrostimulations within a body, the electrode selection being deployable within a body and an adapter 39 connectable to a pulse generator 30 which is mounted to the proximal end of the lead section and generates and outputs predetermined electrostimulation pulses to the electrodes. The medical electrostimulation electrode further comprises an external force mitigating structure which is arranged at least in a region of the lead section disposed within the body and mitigates the delivery of axial displacement of the lead section in a region of the lead section disposed outside the body to the electrodes.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】電極の位置が所望の位置からずれにくい医療用電気刺激電極および医療用電気刺激装置を提供する。【解決手段】遠位端と近位端とを有し長尺のリード部3と、リード部の遠位端に配され体内で電気刺激をするための電極を有し体内に配置可能な電極部10と、リード部の近位部分に配されて所定の電気刺激用パルスを生成して前記電極部へ出力するパルス発生器30に接続可能なアダプタ39とを備え、リード部が、体内に配置されるリード部における領域の少なくとも一部に配され、リード部において体外に配置される領域における前記リード部の軸方向位置変動の電極部への伝達を緩和する外力緩和構造を備える。【選択図】図1
